Alright so my tank was pretty rusty, so I just soaked it in vinegar for a few days. It worked like a charm, all the rust was off the metal, then came time to empty it out. I dumped the vinegar, rinsed some more through, rinsed with water? this might be causing it but I don't know what else to use... then I sloshed some gas around the first time and used WD-40 the second time. AFTER 5 MINUTES THERE'S A TINY LAYER OF SURFACE RUST EVERYWHERE! Am I doing something wrong?
Gas tank won't stay clean! How can I stop flash rust?

Nope, you're not doing anything wrong.
Steel will oxidize in a very short time. A small amount of flash rust isn't going to hurt anything. If you're ready to mount the tank to the bike and fill it up with gas, do that. If you're not, just spray WD40 on it.
DON'T let it sit empty without filling it with gas or treating it some other way.

Diesel or automatic transmission fluid. Pour a bit in, slosh it around, drain the excess. You can use it on the outside as well, apply with a rag. When you are ready to paint, wash the tank with acetone or cheap lacquer thinner until you get zero residue on a clean white cotton rag (cloth diaper is best, shows the slightest amount of residue). The little bit coating the inside of the tank will dissolve into the gasoline and be burned during the combustion process.

Ive used seafoam fogger before and it worked well. I would not recommend WD40 as it is a painters worst nightmare and not even allowed in most production paint shops. i know this to be true for Polaris. LPS_1 is also an alternative to WD40 you could use.
